"I have been buying gear from OPG for several years now and have been always impressed with their customer commitment. Not only is the gear top quality and well priced but their customer service even for a customer half a world away in Brisbane Australia is awesome. Only once has a product failed me and it was a fault of the manufacturer not OPG however Chris was quick to provide a fix free of charge.
I am very comfortable buying on-line from afar with OPG!"
"As for smears and spots on my sensor, using Sensor Clean fluid and Smear Away fluid works amazingly well, and there are no smears remaining on my sensor after cleaning, which is something I can't say about other cleaning solution brands."
